Unemployment insurance is run by each state, so the appeal rules live in state law — but the shape is similar everywhere. There's a short deadline printed on the determination letter, an informal hearing (usually by phone), and a real chance of winning: denied claimants who show up prepared reverse initial decisions all the time. The single most common mistake is stopping the weekly claim filings while the appeal is pending.
Most states allow somewhere between 10 and 30 days from the mailing date of the determination to file an appeal, and the exact deadline is printed on the notice itself. Appeals can usually be filed online, by mail, or by fax; a simple 'I disagree with this determination and request a hearing' is enough to preserve the right.
Winning the appeal only pays benefits for weeks that were properly claimed. States require claimants to keep filing weekly or biweekly certifications — and keep meeting the work-search rules — throughout the appeal. Skipped weeks are generally gone even after a win.
Most hearings happen by phone before a hearing officer (sometimes called a referee or administrative law judge). Testimony is under oath, the employer's side can appear and be questioned, and the officer asks most of the questions. No lawyer is required, though representation is allowed and legal aid offices often handle these free.
The issue is usually why the job ended — misconduct versus a firing that doesn't disqualify, or a quit with good cause. Texts, schedules, write-ups, the resignation or termination paperwork, and witnesses who saw events themselves carry weight; secondhand accounts carry little. Most states let a party ask the hearing office to subpoena documents or witnesses.
A hearing decision can typically be appealed to a board of review, and after that to state court, each with its own short deadline. Overpayment notices that follow a lost appeal often have separate waiver and appeal rights of their own.
